PHYSICAL DATA → CRYPTOGRAPHIC PROOF → TWIX MAINNETTimestamp reality
Timestamp reality
without storing it on-chain.
Sign meter and machine data at the source, store the full records wherever storage is inexpensive, batch commitments into Merkle roots, and use TWIX consensus as the independent timestamp layer.

Attestation is isolated from consensus.
The Device API never accesses the TWIX validator consensus key. Device keys identify devices; a separate EVM wallet signs anchors. A failed meter or storage host cannot alter TWIX consensus.
